Introduction: to evaluate the distribution of von Mises stress in implant-supported restorations, with a temporary pillar of Peek and one of titanium, in three stages of healing (zero day, 1.5 months and 3 months). These evaluations were carried out bfem) method.

Methods: A Tapered Screw-Vent® implant (ref .: TSVB10 Zimmer Dental) of 13 mm length by 3.7 mm diameter was modeled with a 3.5 mm platform, a Peek abutment, a titanium abutment, a screw, a crown

Pmma of an upper central incisor, a cortical and spongy bone with different densities depending on the stage of healing; the Solid Works 2010 cad Software was used, processed and analyzed through the ansys

Software version 14. The von Mises stress distribution was evaluated, applying oblique loads with a magnitude of 200N.

Results: the concentration of stress in the apical spongy bone is 10 times greater on day zero than in the

other moments of healing. The models of abutments in peek at the time 1.5 and 3 months showed almost two times greater efforts in the implant than the models in titanium; similar values wer e observed von Mises when comparing the moment 1.5 and 3 months.

Conclusions: on the zero day of healing the greatest amount of effort is concentrated in the apical portion of the cancellous bone, the Peek pillars transmit more effort to the implant screw, the crestal bone formation helps a better distribution of the stress in the system.
